MULTIPLE TYPE-WRITER PRESS.

To all whom it 'may concern:

Be it known that we, JOI-IN STAFFORD, a subject of the King of GreatBritain, and Oris C. CURRIE, a citizen of the United States, bothresiding at Detroit, county of Vayne, State of Michigan, have invented acertain new and useful Improvement in Multiple Type-Trter Presses, anddeclare the following to be a full, clear, and exact description of thesame, such as will enable others skilled in the art to which it pertainsto make and use the same, reference being had to the accompanyingdrawings, which form a part of this specification.

This invention relates to multiple typewriter presses and its object isa device in which type set up in a flat bed or tray may be used toproduce a result identical in appearance with that produced in atypewriting machine.

It is also an object of the invention to provide means whereby theribbon, through which the impression is made, moves automatically acrossthe face of the type both longitudinally and cross-wise thereof, there-`by maintaining uniformity of color throughout the entire ribbon.

Other objects and novelties of the invention, such as the means forregistering whereby the printing occupies the same relative position onall printed sheets and the means for feeding the blank sheets on to thetype bed, etc., are hereinafter more fully described and claimed.

showing the catch for releasing the lever that reciprocates the platen.Fig. 13 is a plan view of the jaw that removes the printed sheet fromthe type bed. Fig. 14 is a cross sectional view of the platen and thefeed roll showing, in dotted lines, the position assumed by the partswhen feeding paper on to the type bed.

Similar letters refer to similar parts throughout the drawings andspecification.

A, A indicate the side frames which are supported by the cross Ybars a,a', etc., in ways fio in which side frames the type bed B isreciprocatingly mounted. The type bed, as shown in Figs. 2 and 3, isadapted to carry a tray g in which the type z' are set up.

The reciprocation of the bed is accomplished by means of the connectingrod r, one end of which is attached to the cam wheel C2 on the mainshaft C, t-he opposite end being pivotally attached to a lever L whichis keyed to the shaft a mounted in bearings in the frames A, A. Thelever L is also keyed to the shaft a and to the free ends of the leversL and L are pivotally attached the connecting rods or bars o and o, theopposite ends of which are attached to lugs on the bed B. The rotationof the shaft C and cam wheel C2 consequently reciprocates the bed.Spools S and S are mounted on shafts 1^ at each end of the bed B and areadapted to carry the ribbon R across the face of the t-ype ashereinafter more fully described. As shown in Figs. 1 and 2, al platen Pis reciprocatingly mounted above the type bed B. The type bedreciprocates in a horizontal plane and the platen reciprocates in avertical plane and during the forward movement of the bed the platen isheld in contact therewith and during the return movement of the bed isheld out of contact therewith. The platen is also rotatable on the shaftP by means of the rack d, on the bed B, and the gear G loosely mountedon the collar Q2 attached to the platen. The teeth of the gear are ofsuch length that they are never out of mesh with the rack during thereciprocating movement of the platen. Therefore, in order that the rackmay not rotate the platen during the return movement of the bed, thegear G is not directly connected to the platen but is provided with aclutchl whereby said gear p rotates the platen during the forwardmovement of the bed and does not rotate the platen during the returnmovement of the bed, although the gear itself does rotate.

The shaft P, on which the platen is mounted, is supported by the hangers/L and it', one on each side of the machine, in a recess in the framesprovided therefor. The lower end of each hanger L and It is pivotallyconnected to levers f/ and e" respectively, which are pivoted on theside frames at y' and j. Also pivoted at y' and j are the levers and 7ccarrying the cam rollers m and m which ride on the cam wheels C and G2.Both the levers z' and 7c have upwardly extending ends 2 and 7a2 and athumb screw n is threaded in the end 752 of the lever 7c and bearsagainst the dog Zt pivoted on the end 2 of the lever z'. The levers z"and are also provided with upwardly extending ends and attached partsand have the same design and function as the levers i and 7c,consequently the description of one set of levers will do for both. Thedog Z2 has a thumb piece Z5 by means of which it may be withdrawn frombetween the end of the thumb screw and the end 2 of the lever z' asshown in dotted lines in Fig. 12. The cam roller m on the lever rides onthe cam C', as heretofore stated, and, by means of the thumb screw a,lever c', and the hanger it, intermittently brings the platen intocontact with the type bed. The levers z" and 7*." are actuated at thesame time as the levers z' and 7.a, but are connected to the oppositeend of the platen shaft, by reason of which the platen has an equalpressure on the type bed throughout its length. lf for any reason it isdesired to operate the machine without reciprocating the platen, the dog(Z4 on the upwardly extending part of the levers t' and c" is raised outof the path of movement of the thumb screws a, allowing` the levers 7cand 71: to move freely on their pivots and j. The adjusting screw n.provides a means whereby the looseness of the joints and the spring ofthe levers may be taken up and the platen held firmly when in contactwith the bed.

In order to prevent the platen from being forced down between the linesof type by the pressure produced by the above described mechanism, andalso to accurately gage the ink impression resulting therefrom, stops s,s, are provided against which the platen shaft P rests when in theprinting position. Brackets B are bolted to each frame below the end ofthe shaft P and are provided with a recess in which the hangers /t andz. reciprocate. The stops s, which are simply cap screws, are located intapped holes s2 in the brackets and cap screws s are inserted in theholes from the lower side forming a lock for the screws s. By adjustingthe lock screws S and the stops a and thumb screws a heretoforementioned, a greater or less pressure is produced between the platen andthe bed. Springs s3 are mounted on the brackets and are adapted to holdthe platen out of contact with the bed.

A. feed roller F is mounted above the platen in slots IL10 in thehangers 71, and It and a. feed table T is attached to a cross bar of theframe in a proper position for the insertion of blank sheets of paperbetween the feed roller and the platen. The feed roller has areciprocating motion in the slots in the hangers toward and away fromthe platen, which is accomplished by mechanism hereinafter described,and during the time the roller is lifted away from the platen the paperis inserted therebetween and rests against the paper stops S2, S2 and asthe feed roller F is brought into contact with the paper, the stops S2are lifted out of the path of movement thereof allowing the paper to befed forward due to the rotation of the platen and the roller. A shield His supported on the roller F by the hangers 7L and rests against theplaten as shown in Figs. 2 and llt and a slight tension between theshield and the platen is produced by the spring s4 attached to thehollow cross bar b5 as shown. The shield provides a means for properlyplacing` the paper on the type bed and the stops S2 provide a means ofregistering whereby the printing occupies the same position on all theprinted sheets, the utility of which is in facilitating the insertion ofnames and dates, etc., by means of a typewriter, on such matter ascircular letters. The feed roller is raised from contact with the platenby the rock arm a5 and connecting bar 0G attached to the cam lever c,which is actuated by the cam C3. The cam lever co is provided with aroller r3 against which the cam rides. The rock arm a5 is attached tothe rock shaft ai passing through the hollow cross bar b5 and, on theopposite end, the shaft a7 is provided with a rock arm as. The rock armst5 and as are positioned below the projecting ends of the feed roller Fas shown in Fig. 3, thus providing means at each end of the feed rollerfor lifting it out of contact with the platen. The stops S2 are actuatedby the cam lever c6 by means of the connecting bar a2, rock arm @10, androck shaft cl2. The connecting bar a is slotted at the end to which thecam lever cG is attached, as said lever has a greater movement than isnecessary to operate the stops, and, as is shown in Fig. 10, a spring sis mounted on the shaft C412 which tends to hold the stop S2 in positionto stop the paper when inserted between the feed roller and the platen,and the cam lever only serves to raise the stops out of contact with theplaten and allow the paper to be fed on to the bed. The spring 37, whichis attached turns the cam lever to its normal position after being actedupon by the cam C3, and during the latter part of the movement of thecam lever c, caused by the action of the spring sT, the stops are raisedout of contact with the platen bythe slotted connecting bar a9. `Whenthe cam lever 0G is raised by the cam C3, the feed roller F is raisedout vof contact with the platen by the vrock arms a5 and as asheretofore described and the 'stops S2 are brought into contact with theplaten by the spring s6 on the shaft 0a12 shown in Fig. 10. In itsnormal position as shown in Fig. l, the cam lever c holds the stops S2out of contact with the platen as the spring S7 is of sufficientstrength to Overcome the action of the spring s which tends to hold thestops S2 in contact with the platen. The utility of the slot in the bara is not only in allowing the lever c6 to move upward withoutinterfering vwith the described action of the stops S2, but, on thereturn movement, allows the feed roller F to come in contact with theimpression sheet (which has been inserted while the roller was raised)before the end of the lever c strikes the end of the slot and lifts thestops out of contact with the platen. If the movement of the feed rollerF and the stops S2 were simultaneous, the sheet might become displacedbefore the roller was in place, but, by the arrangement above described,the stops remain in position until the roller comes in contact with thesheet thereby preventing a displacement of the sheet. The feed roller Fis grooved at f, f, to allow the stops S2 to be properly positioned inrelation to the platen.

It is evident that the paper must be inserted between the platen and thetype bed prior to what may be termed the printing movement thereof andalso before the platen is in contact with the bed. To accomplish thisresult, a ball clutch Q is provided at one end of t-he platen, looselymounted on a collar g attached to the platen, as shown in Figs. 3 and1l. The balls g rest in pockets g2 in the member Q, the outer walls ofwhich are eccentric to the shaft P and collar Q. If the member Q berotated in the direction of the arrow shown in Fig. 1l, the balls Q bindbetween the eccentric walls and the collar and therefore rotate theplaten. The gear G, on the opposite end of the shaft, is provided wi-tha clutch similar to the one above described. The clutch Q is providedwith a metal tape g3 0n its periphery which is connected to a lever g4pivoted on the frame A. The lever gt is connected to the cam lever Q bythe connecting bar g5 and the cam lever is actuated by the roller r6 onthe balance wheel W which roller r6 contacts the cam face Q3 of thelever Q once every revolution of the shaft C. The roller to the rock arma and the frame A, re-7 and balance wheel are shown in dotted lines inFig. l and in full lines in Fig. 3. The roller is so placed on thebalance wheel that the cam lever Q is actuated and the platen rotatedprior to the finish of the return stroke of the reciprocating bed andthus places the paper in the proper printing position before the platenis in contact with the bed. The member Q is provided with a coiledspring Q6 that is placed under tension when the platen is rotated by thetape and returns said member Q, lever g4, and cam lever Q to theirnormal position after being acted upon by the cam roller r6. One end ofthe spring is attached to the member Q and the opposite end is attachedto the frame A. The spring is shown in section in Fig. 3.

The cams C and C2 that bring the platen into contact with the type bedare timed to produce said contact slightly prior to the forward orprinting stroke of t-he bed B. The platen is then rotated by the rack 0land the gear G in the same direction as iS produced by the clutch Q. Theclutch Q rotates the platen, which with -the coacting parts brings theend of the impression sheet to the printing position between the platenand the bed prior to the co-n-tact of the platen kwith the bed, and therack Z and gear Gr rotate the platen during the printing movement of thebed. The platen is in contact with the bed during said printing movementand the coaction therebetween continues the feeding of the impressionsheet on to the bed. At the finish of the printing stroke of the bed,the prin-ted sheet is grasped by the jaws J and J and, as the bedretreats, the paper falls into the pan or receiver U provided for suchpurpose. The aw J is operated by rock shaft js, rock arm j?, connectingrod js, bell crank j", and rod jl attached to the lever lo as shown inFig. 1. It will thus be seen that, as the bed completes the forwardstroke and the lever 7c releases the platen from contact with the bedand the paper thereon, the jaw grasps the paper, as shown in Fig. 2, andas the bed retreats the paper naturally falls into the receiver shown indotted lines in Fig. 2.

As heretofore stated, the ribbon has a movement both longitudinal andcrosswise of the bed, the utility of which is in maintaining uniformityof color in the ribbon. It is evident -that forms set up in the tray maynot all be of uniform width and, if no provision was made for acrosswise movement of the ribbon, the central part thereof would becomeworn with those forms that were narrow and, when a wider form was usedthe resulting impression would be much heavier on the edges than in thecentral part. With a gradual shifting of the ribbon crosswise of thebed, this defect is eliminated as width. The ribbon movement is producedby the pawls e, e', and e2 acting on the ratchets es, et, and e5. Thepawls are attached to the reciprocating bar E and are spring controlledas shown in Fig. 4. The ratchets e3 and @5 are mounted on the shafts rone at each end of the type bed B and the ratchet e* is mounted on theshaft 0G near the center of the bed. rl`he shafts r carry the ribbonspools S, S and have a keyway 102, shown in Figs. 5 and 7, in which thepin w3 engages when the spool is locked to the shaft. rlhe pin isretained in position by the spring 'w'L attached to the end of the spooland said pin is bent as shown, and when the horizontal part is parallelwith the shaft, it will drop into the notch L05 on the end piece of thespool and the lower end will enter the keyway @U2 and consequently lockthe spool to the shaft. The keyway w2 is of sutlicient length to allowthe spool to be moved longitudinally on the shaft. To release the spoolfrom the shaft, the pin w3 is raised out of the notch 105 and the bentend turned at right angles to the axis of the shaft. rPhe lower end isthen out of the keyway and the shaft is free to revolve without rotatingthe spool. The spring wt retains the pin in either position in which itmay be placed. An examination of Fig. 4L will show that a reciprocationof the bar E rotates both shafts 1 on which the spools S are mounted,consequently one of the spools must be free from the shaft in order thatthe ribbon may have a movement longitudinal of the bed B. To reverse themovement of the ribbon, the free spool is locked to its shaft and theopposite one released from its shaft.

The bar E is carried by the reciprocating bed B and, as is shown inFigs. l; and 8, the actuating bar X is moved longitudinally of the bed,and, by means of the bent and notched end acting against the pin a2 inthe bar E, moves said bar E longitudinally of the bed. This movement ofthe bar places the spring rc under tension which returns the parts totheir normal position when released by the forward movement of the bed.The bar X is held on the bed by the screw in the slot fc3, and the bar Xis also provided with a pin au* which, as the bed approaches the finishof the return stroke, strikes against the lug :e5 on the frame and asthe bed continues its movement the bar X slides longitudinally of thebed and actuates the bar E as above described.

The movement of t-he ribbon crosswise of the bed is caused by the pawl ewhich intermittently rotates the ratchet e4 and shaft e6. A barrel camel is mounted on the shaft e and in the cam groove es a pin 'g/ rides.The pin ,i/ is fastened in the lever Y as shown and the lever Y isprovided with a forked end y2 adapted to encircle the end of the lever Yin which the pin is located. The levers Y and Y are otherwiseessentially alike. The levers are attached to the type bed B at 3/3 andy'l as shown in Fig. 2 and have forked ends g/5 and y that are adaptedto ride in a groove e on the spools as shown in Fig. 5. It is thereforeevident that a rotation of the barrel cam e7 will move the spools S, Slon gitudinally on their shafts r', thereby proA ducing a movement ofthe ribbon crosswise of the type bed. If the type form set up in thetray is as wide as the ribbon, it becomes unnecessary for the ribbon tohave a movement crosswise of the bed and to stop said movement of theribbon, the pawl e is raised out of engagement with the ratchet e* bymeans of a latch Z attached to the bed as shown in Fig. t. A bottom viewof the latch is also shown in Fig. 9. The latch is provided with a slote in which is the screw e2 holding it in position on the bed. A bent endof the latch is adapted to lift the pawl e out of engagement with theratchet et when said latch is moved longitudinally of the bed. A bentend e* provides a means whereby the latch may be moved and the screw e2holds the latch in whatever position it may be placed.

In operation, the feed roller F is raised out of contact with the platenand the stops S2 brought into contact therewith prior to the printingmovement of the bed B. During this interval the blank paper is insertedbetween the feed roller and the platen and rests against the stops S2.As the feed roller is again brought into contact with the platen, thestops are raised out of contact therewith and the cam lever Q isactuated which, in turn, actuates the clutch Q. rlhe clutch Q rotatesthe platen and feed roller and feeds the paper forward during the latterpart of the return movement of the bed. The shield H guides the paper onto the bed between the platen and the bed, the platen being out ofcontact with the bed during the entire backward or return movementthereof. At the finish of the return stroke, the ribbon is moved forwardby the slide bar X and coacting mechanism heretofore described. As thetype bed is about to start on its forward or printing stroke, the camsC', C2 bring the platen into printing contact with the bed by means ofthe cam rollers m, m and connected levers. During this forward stroke ofthe bed the platen is ro tated by means of the rack and gear heretoforedescribed in detail. rJhe rotation of the platen continues to feed thepaper on to the bed and, as the bed reaches the limit of its forwardmovement, the platen is released from its contact with the bed and thejaws J and J grasp the printed sheet of paper by reason of the camrollers dropping on to the lower part of the cams C and The springs S3hold the cam rollers in contact with the cams. rlhe jaw el isstationary,

being mounted on the inner ends of the tubes T2, T3 as shown in Fig. 13.The tubes are mounted in brackets Z915 on the side frames, as shown inFigs. 1 and 13. The jaw J is mounted on the rock shaft je which islocated in the tubes as shown. As the bed begins its return movement, itretreats from under the paper, allowing it to drop into the receiver Uwhen released by the aw at the nish of the stroke.

16. In a multiple typewriter press, a reciprocating bed mounted in aframework and adapted to hold t-he printing form, an ink ribbon carriedby t-he bed and covering the printing form, a platen mounted in hangersin the framework, said hangers having a reciprocating movement wherebypressure is produced between the platen and the printing' form duringthe printing movement of the bed, a roller carried by the hangers andcoacting with the platen to feed the impression sheet into printingposition during the return movement of the bed, said roller having areciprocating movement independent of the reciprocating movement of thehangers whereby an impression sheet may be inserted between the rollerand the platen, stops arranged to be brought into contact with theplaten during the time the roller is out of contact therewith therebylimiting the distance the. impression sheet may be inserted between theroller and the platen, the engagement of the impression sheet betweenthe platen and the printing forni constituting a means whereby theprinting movement o-f the bed causes the impression sheet to be fed onto the printing form.

17. In a multiple typewriter press, a reciprocating type-carrying bedmounted in a framework, an ink ribbon carried by the bed and coveringthe printing surface, a platen mounted in hangers carried by theframework, means for reciprocating the hangers whereby pressure may beproduced between the platen and the bed during the printing movementthereof, a roller carried by the hangers, stops carried by theframework, a spring tending to hold the stops in contact with theplaten, a cam actuated lever adapted to reciprocate the roller in thehangers and subsequently raise the stops out of contact with the platen,said roller providing a means for introducing an end of an impressionsheet between the platen and they bed, the engagement of the sheettherebetween constituting a means for feeding the sheet onto the bed,and means for removing the printed sheet from the bed.

18. In a multiple typewriter press, a reciprocating bed mounted in aframework and adapted to hold the printing form, an ink ribbon carriedby the bed and arranged to be intermittently moved across the printingform both longitudinally and transverselythereof, a platen mounted inhangers in the framework, said hangers having a reciprocatingmovementwhereby pressure is intermittently produced between the platenand the printing form, a roller carried by the hangers and coacting withthe platen to feed the impression sheet into printing position, saidroller having a reciprocating movement independent of the reciprocatingmovement of the hangers thereby lifting the roller out of contact withthe platen and allowing an impression sheet to be inserted between theroller and the platen, said coaction of the roller and the platen being'prior to the printing movement of the bed, stops arranged to be broughtinto Contact with the platen during the time the roller is out ofcontact therewith thereby limiting the distance that the impressionsheet may be inserted between the roller and the platen, and meanswhereby the printing movementof the bed causes the impression sheet tobe fed on to t-he printing form, substantially as shown and described.

19. A multiple typewriter press comprising a framework, a reciprocatingbed mounted therein, a rack on said bed, a tray adapted to hold theprinting form, said bed being adapted to receive said tray, an inkribbon carried by the bed and arranged to be intermittently moved acrossthe printing form, means for so moving the'ribbon, a platenreciprocatingly mounted in the framework, a feed roller held incooperative relation with the platen, means for reciprocating the platenthereby intermittently bringing the platen into contact with theprinting form, a clutch at one end of the platen adapted to rotate theplaten, means for operating the clutch and rotating the platen and feedroller prior' to the printing movement of the bed thereby causing theimpression sheet to be fed into printing position, a spring adapted toreturn the clutch and coacting parts to inoperative position, a clutchon the opposite en d of the platen having a gear on its peripherymeshing with the rack on the bed whereby the platen may be rotatedduring its Contact with the printing form and thereby feed theimpression sheet on to the printing form, and means for removing theprinted sheet from the form, substantially as shown and described.

Q0. il multiple typewriter press comprising a reciprocating, typecarrying bed, an impression ribbon carried on spools mounted on shaftscarried by the bed, means on the spools whereby they may be locked tothe shaft, means for rotating the shafts thereby moving the ribbonlongitudinally over the type bed, said means comprising ratchets on saidshafts actuated by pawls carried by a reciprocating bar mounted on thebed, means for reciprocating said bar, means for producing an endwisemovement of the spools on their shafts comprising a shaft and ratchetactuated by a pawl on the reciprocating bar, a cam on the shaft, leverspivoted on the bed, said levers being oscillated by the cam, one end ofeach lever being connected to a spool whereby said oscillation moveseach spool endwise on its shaft and thereby produces a movement of theribbon transversely of the type bed simultaneously with its movementlongitudinally thereof, a platen reciprocatingly mounted in theframework whereby pressure is intermittently produced between the platenand the type bed, means on the platen whereby it may be rotated, meanscoacting with the platen whereby said rotation feeds the impressionsheet to printing position, and means whereby the printing movementcauses the .impression sheet to be fed onto the bed, substantially asshown and described.

In testimony whereof, we sign this specitication in the presence of twowitnesses.
